Hey there, don't know if this question has been addressed. I am a cat 1 xc mountin bike racer and now wants to get more serious and train with power. My dilemma is what bike I should put the meter on (still have not purchased meter) I have been riding more mtb than road and I am planning on racing LT 100 in aug. If I put it on my mtb which one( 29er HT, or xc FS 4" or FS 3.5 with a 1x9? Any help would be helpful, I can't afford to buy two units. Thanks
